                            Due September 30, 2001

$500,000.00                                                      June 18, 2001

     FOR VALUE RECEIVED, Hawaiian Natural Water Company, Inc., a Hawaiian
corporation (the "Corporation"), promises to pay to the order of AMCON
Distributing Company, a Delaware corporation (the "Holder"), the principal sum
of Five Hundred Thousand and NO/100 Dollars ($500,000.00), on September 30,
2001 (the "Maturity Date"), together with interest in the amount and manner
hereafter provided.

     IT IS FURTHER AGREED THAT:

     1.  Interest.  The Corporation promises to pay interest on the principal
amount of this 10% Secured Convertible Note (the "Note") at the rate per annum
of ten percent (10%), compounded quarterly.  Interest will be computed on the
basis of a three hundred sixty (360) day year of twelve (12), thirty (30) day
months.  Interest will be paid quarterly on January 1, April 1, July 1, and
October 1 of each year and at maturity, with the first such interest payment
to be made on July 1, 2001.

     2.  Method of Payment.  Except with respect to the rights of conversion
provided herein, and subject to Section 3 hereof, the Corporation will pay
principal and interest by wire transfer of immediately-available money of the
United States, or other form of payment of immediately available money of the
United States as the Holder may direct the Corporation, that at the time of
payment is legal tender for payment of public and private debts.  Information
for making the wire transfers will be provided in writing by the Holder to the
Corporation.  If any payment hereunder becomes due and payable on a day other
than a business day, the due date thereof shall be extended to the next
business day and, with respect to payments of principal, interest thereon
shall be payable at the applicable rate during such extension.

     3.  Right to Prepay.  The Corporation shall have the right to prepay all
or any part of the Note; provided, however, that (i) the Corporation must give
written notice to the Holder of its intention to make any such prepayment not
less than five (5) and not more than ten (10) business days in advance of such
prepayment, which notice must include a representation that the funds to
effect the prepayment are legally available for that purpose and that
representation must be supported by evidence reasonably satisfactory to the
Holder that such funds will be provided to the Corporation at the time
specified in the notice for prepayment, and (ii) during the period following
that notice and prior to the actual prepayment, the Holder shall be entitled
to exercise the conversion privilege set forth in Section 4(a) hereof, if the
right to convert specified therein is available by its terms, or Section 4(b)
hereof.

     4.  Right to Convert.

         (a) At any time before the close of business on the Maturity Date but
     after the earlier of (A) termination of the Fourth Amended and
     Restated Agreement and Plan of Merger (the "Merger Agreement"), dated as
     of June 18, 2001, among the Corporation, the Holder and AMCON Merger Sub,
     Inc.("Merger Sub") or (B) the occurrence of an Event of Default, the
     Holder may convert the outstanding principal balance and unpaid accrued
     interest of this Note into fully paid and non-assessable shares of Series
     C Convertible Preferred Stock, par value $1.00 per share, of the
     Corporation (the "Preferred Stock").  The price at which shares of
     Preferred Stock shall be delivered upon conversion (herein called the
     "Preferred Conversion Price") shall be $1.00 per share of Preferred
     Stock.

         (b) At any time before the close of business on the Maturity Date,
     the Holder may convert the outstanding principal balance and unpaid
     accrued interest of this Note into fully paid and non-assessable shares
     of common stock of the Corporation (the "Common Stock").  The price at
     which shares of Common Stock shall be delivered upon conversion shall be
     $0.40 per share; provided, however, that if the Corporation shall at any
     time increase or decrease the number of its outstanding shares of Common
     Stock or change in any way the rights and privileges of such shares by
     means of the payment of a stock dividend or any other distribution upon
     such shares payable in Common Stock, or through a stock split,
     subdivision, consolidation, combination, reclassification or
     recapitalization involving the Common Stock, then the price at which
     shares shall be delivered upon conversion shall be proportionately
     increased or decreased, as the case may be, to avoid dilution of the
     number and kind of shares to which the Noteholder is fairly entitled upon
     conversion of the Note.

         (c) This Note may be converted in whole, but not in part, into
     Preferred Stock or Common Stock or a combination thereof (referred to
     collectively as the "Conversion Shares") based on the terms set forth in
     subsections (a) and (b) of this Section 4, as the case may be.

     5.  Mechanics of Conversion. If the Holder desires to exercise such right
of conversion, such Holder shall give written notice to the Corporation in the
form attached to this Note as Exhibit A (the "Conversion Notice") of that
Holder's election to convert a stated whole dollar amount of outstanding
principal balance and unpaid accrued interest of the Note into shares of
Preferred Stock, and/or Common Stock, as the case may be, and surrender to the
Corporation, at its principal office or at such other office or agency
maintained by the Corporation for such purpose, this Note.  The Conversion
Notice shall also contain a statement of the name or names (with addresses) in
which the certificate or certificates for Preferred Stock and/or Common Stock,
as the case may be, shall be issued.  Notwithstanding the foregoing, the
Corporation shall not be required to issue any certificates to any person
other than the Holder thereof unless the Corporation has obtained reasonable
assurance that such transaction is exempt from the registration requirements
of, or is covered by an effective registration statement under, the Securities
Act of 1933, as amended (the "Act"), and all applicable state securities laws,
including, if necessary in the reasonable judgment of the Corporation or its
legal counsel, receipt of an opinion to such effect from counsel reasonably
satisfactory to the Corporation.  In no event would such opinion be required
if the shares of Preferred Stock and/or Common Stock, as the case may be,
could, upon conversion, be resold pursuant to Rule 144 or Rule 144A under the
Act.  As promptly as practicable, and in any event within two business days,
after the receipt of the Conversion Notice (the "Date of Conversion") and the
surrender of the certificate or certificates representing the Conversion
Shares, the Corporation shall issue and deliver, or cause to be delivered, to
the Holder or his nominee or nominees, a certificate or certificates for the
number of shares of Preferred Stock and/or Common Stock, as the case may be,
issuable upon the conversion of this Note.  Such conversion shall be deemed to
have been effected as of the close of business on the Date of Conversion and
the replacement Note, and the person or persons entitled to receive the shares
of Preferred Stock and/or Common Stock, as the case may be, issuable upon
conversion shall be treated for all purposes as the holder or holders of
record of such shares of Preferred Stock and/or Common Stock, as the case may
be, as of the close of business on such date.

     6.  Fractions of Share.  The Corporation shall not be required to issue
fractions of a share or scrip representing fractional shares of Preferred
Stock and/or Common Stock, as the case may be, upon the exercise of any
conversion right hereunder.  If any fraction of a share of Preferred Stock
and/or Common Stock, as the case may be, would, except for the provisions of
this Section 6, be issuable upon any conversion exercise, the Corporation
shall pay a cash adjustment in respect of such fraction, equal to the value of
such fraction based on the Conversion Price per share of Preferred Stock.

     7.  Security.  The obligations herein are secured by the security
interest granted pursuant to that certain Second Amended and Restated 10%
Convertible Note in the principal sum of $350,000.00 payable by the
Corporation to Holder due on September 30, 2001 (and as such note may be
further amended and/or restated).

     8.  Corporation Covenants.  The Corporation represents, warrants,
covenants and agrees that:

         (a) Any shares of Preferred Stock and/or Common Stock, as the case
     may be, delivered upon conversion of this Note shall, at the time of
     delivery of the certificates for such shares of Preferred Stock or Common
     Stock, be validly issued and outstanding and fully-paid and non-
     assessable shares of Preferred Stock or Common Stock free from taxes,
     liens and charges with respect to their purchase.  Without limiting the
     generality of the foregoing, the Corporation covenants and agrees to take
     any necessary actions to assure that the par value per share of the
     Preferred Stock is at all times equal to or less than the then current
     Conversion Price per share for the Preferred Stock issuable pursuant to
     this Note.  The Corporation further covenants and agrees that it will pay
     when due and payable any and all federal and state original issue stock
     taxes, if any, which may be payable in respect of the issue of the shares
     of Preferred Stock or Common Stock upon the conversion of this Note or a
     part hereof.  Except for an amendment required pursuant to the foregoing
     sentence, the Certificate of Designation, Preferences and Rights of the
     Preferred Stock shall not be amended without the prior written consent of
     the Holder.

         (b) The Corporation shall at all times reserve and keep available a
     number of its authorized but unissued shares of Preferred Stock and
     Common Stock which will be sufficient to permit the full exercise of this
     Note.  If at any time the number of authorized but unissued shares of
     Preferred Stock or Common Stock is not sufficient for this purpose, the
     Corporation shall take such corporate actions as may be necessary to
     increase its authorized but unissued shares of Preferred Stock and/or
     Common Stock, as the case may be, to a number of shares sufficient for
     such purpose.

         (c)  (i)  The Corporation is duly organized as a corporation under
     the laws of the State of Hawaii, it is authorized to transact business in
     all jurisdictions where the conduct of its business requires it to be
     qualified, and it is duly authorized to execute, deliver and perform
     under this Note without the necessity of obtaining any consents or
     approvals of, or the taking of any other action with respect to, any
     governmental agency or third party; and

              (ii) The financial statements submitted to Holder fairly present
     the financial condition of the Corporation as of the date of this Note
     knowing that Holder has relied thereon in granting the Loan, there have
     been no material adverse changes in the financial condition of the
     Corporation since the date of said financial statements, the Corporation
     has no material obligations, financial or otherwise, not disclosed to
     Holder, and at the present time there are no material, unrealized or
     anticipated losses from any present commitment of the Corporation.

         (d) The Corporation shall give written notice to the Holder at least
     10 days prior to establishing a record date to determine the stockholders
     of record entitled to vote on the merger contemplated by the Merger
     Agreement in order to permit the Holder to exercise the right to convert
     this Note and vote upon such merger and to receive merger consideration
     pursuant to such merger.

     9.  Rights of Holder.  The Holder of this Note shall not be entitled to
vote or receive dividends or be deemed the Holder of Preferred Stock or Common
Stock of the Corporation for any purpose, nor shall anything contained in this
Note be construed to confer upon the Holder, as such, any of the rights of a
stockholder of the Corporation or any right to vote for the election of
directors or upon any matter submitted to stockholders at any meeting thereof,
or to give or withhold consent to any corporate action (whether upon a merger,
conveyance or otherwise) or to receive notice of meetings, or to receive
dividends or subscription rights or otherwise until the right to convert this
Note shall have been exercised and the Preferred Stock or Common Stock
purchasable upon the exercise hereof shall have become deliverable.

     10. Rights Upon Exercise.  Irrespective of the date Preferred Stock or
Common Stock is issued and of delivery of certificates for any shares issuable
upon the exercise of the conversion privilege under this Note, each person in
whose name any such certificate is issued shall for all purposes be deemed to
have become the holder of record of the shares represented thereby on the Date
of Conversion.

     11. Investment Representation; Transfer.  The Holder hereby represents
and warrants to the Corporation that it has purchased this Note and will
purchase shares of the Preferred Stock and/or Common Stock, as the case may
be, of the Corporation issuable upon conversion hereof for investment purposes
only and not with a view to the distribution thereof.  The Holder acknowledges
that it has been advised by the Corporation that neither this Note nor the
Conversion Shares has been registered under the Securities Act of 1933 or any
state securities law for the reason that no distribution or public offering of
this Note or the Conversion Shares is to be effected.

     12. Dissolution.  In case any voluntary or involuntary dissolution,
liquidation or winding up of the Corporation shall at any time be proposed,
the Corporation shall give at least sixty-two (62) days' prior written notice
thereof to the Holder stating the date on which such event is to take place
and the date (which shall be at least sixty-two (62) days after the giving of
such notice) as of which the holders of Preferred Stock or Common Stock of
record shall be entitled to exchange their Preferred Stock or Common Stock for
securities or other property deliverable upon such dissolution, liquidation or
winding up.

     13. Default.  Any one or more of the following shall be events of default

         (a) Default shall be made:  (i) in the payment of the principal or
     interest under this Note when due; or (ii) in due observance or
     performance of any other agreement contained in this Note, which is not
     remedied within fifteen (15) days after notice to the Corporation;

         (b) Any warranty, representation or agreement made or furnished to
     the Holder by or on behalf of the Corporation in the Merger Agreement
     proves to have been false in any material respect when made or furnished;
     or

         (c) The insolvency of the Corporation, the making of a general
     assignment for the  benefit of creditors, or the filing of any voluntary
     or involuntary petition or commencement of any proceeding by or against
     the Corporation under any bankruptcy or insolvency laws.

Upon the occurrence of one or more Events of Default and at any time
thereafter, the Holder may, by notice in writing to the Corporation, declare
the entire outstanding principal amount of the Note to be, and such entire
principal amount of the Note shall thereupon become forthwith, due and payable
in full together with interest accrued thereon, anything in this Note to the
contrary notwithstanding.  Upon the occurrence of one or more Events of
Default, the Corporation agrees to pay out-of-pocket expenses, including
reasonable attorneys' fees and legal expenses, whether or not suit is
commenced, incurred by the Holder.  If an Event of Default shall have occurred
and has not been cured by the Corporation within 90 days after the occurrence
thereof, then thereafter this Note shall accrue interest at the rate per annum
of eighteen percent (18%), compounded quarterly and computed in accordance
with Section 1 of this Note.
